摘　　要：针对火灾疏散过程中的多出口选择问题,本文提出一种基于分布估计算法的求解策略。首先,综合考虑路径最短和威胁数目最少建立多出口选择模型,通过罚函数方法处理约束建立适应度函数。其次,采用分布估计算法在离散空间进行优化求解。仿真验证了算法的有效性。One strategy for multi-exit selection during fire evacuation based on the estimation of distribution algorithm（EDA） is proposed in this paper.The selection model is given in view of the shortest route and the minimum number of the threats during the evacuation.Penalty function is taken to convert restriction to the evaluation function while EDA is adopted to solve the optimization problem with its good performance on the basis of statistics.The effectiveness of the strategy is verified by simulation.
